Traditional wireless sensor networks (WSNs) are consist of sensor nodes with limited battery energy power. Due to rapid development of wireless power transfer technology, sensors can be recharged when they are within limited charging ranges of mobile devices and we call this kind of network rechargeable WSN(RWSN). In RWSN, mobile chargers (MC) are employed to recharge the sensor nodes. However, since...
Firefly algorithm is a new nature-inspired algorithm and has been used gradually in solving optimization problems. a path planning method based on firefly algorithm was proposed. After the detailed analysis of the basic algorithm, random parameter and absorption parameter were designed to be adaptive, and this can improve the solution quality and convergence speed of the firefly algorithm. According...
